To the Editor of the Monthly Magazine. 
ayOuR correfpondent Cambrobrittanicus (p. 18, No. XIII) ftates a feeming dif- 
ficulty in Afironomy; and enquires how it is to be obviated, confiftently with 
the generally received doétrine of the planetary .motions, particularly that of the 
earth, viz. as to the different degrees of heat received by the earth from the fun, 
wijea at the greateft and leaf diftances in the annual orbit. .Deubrlefs, fir; fuch 
communications, difcuffed in a popular way, muft.be very generally ufeful, and well 
adapted to the nature of your erudite and liberal Numbers. 
Cambrobrittanicus ftates the cafe and circumftances of his difficulty very fairly 
and plaufibly, giving a jut ftatement of the elliptic orbit of the earth, in her ‘an- 
nual motion, with-its eceentricity, and the-greateft and leaft-diftances of the earth 
from the fun, at the places of the aphélion "and perihelion, which happen. at the 
times of the~{fummer and winter folftices. Thefe diftances he juftly makes to be 
nearly 96§ millions and 93} millions of miles, differing by 32 millions of miles, or 
about the 3oth part of the whole diftance. Now Cambrobrittanicus thinks fach a 
confiderable difference as upwards of three millions of miles, in the fun’s diftance 
from the earth, ought to manifeft itfelf fenfibly in the difference in the a ees of 
heat, felt at thofe times, viz. about June 21, in north latitude 23° 28, and Decem- 
ber 21, in fouth latitude, 23° 28’, the places to which the fan is vertical at thofe 
times. And he thinks this difference of heat ought to be the more'evident, as com
